AEG GASSTOVE FROM MAKRO

I need assistance please. I have bought a gasstove from Makro Wonderboom Pretoria on 11/11/2016 for the amount of R15 098.00 iincluding a wxtended warranty. From the very start the stove started giving trouble. About 6 weeks ago the thermofan stopped working. As this is now in the extended warranty period Makro send me a private company by the name of Panaserve. Two technicians came to look at the stove and broke the one leg of the stove. So now the stove is standing on 3 legs;. they promised they will be back very soon to fix the stove. 2 weeks later I phoned Panaserve to find out what the situation is because no one came back. Next day a new technician came. He told me he is not workiing for Panaserve but that they contract him in if they cannot fix a problem. hen gave me his number Nkosi ********** 335. after two weeks i phoned him and he told me that he cannot get hold of the part but I must phone Diane at Panaserve tel o 011 n ********** /9 because she is busy to obtain approval from Makro to give me credit as the stove is irreperairable. I phoned Diane and she said she will phone me back within half an hour. She never phoned back. I then wrote Panaserve an email stating my problem and I would like an answer. ********** immediatly mailed me back and said he is busy with Makro i must just bear with him. A few days later (yesterday) i went to Makro to see if i can find out what is going on. The salesman there told me that i will receive a sms from Panaserve and then i bring that in and i can choose a new stove. he said it shouldn''t take more than 3-4 days. I then came back and contacted Anthony at Panaserve and told him the story. He now say that he is a BEE company and he cannot do that. He is waiting for Makro to come back to him. I am desperate and do not know where to go for assistance. Can you help me please? My name is Johanna Elizabeth Appelgryn id 590 ********** 084 adress 520 Taljaardstreet Da****rt pretoria. My reference number at Panaserve is J26563
